This doesn’t work.
My small keyboard is stuck and I tried a two finger expansion to get the big one back but it doesn’t do anything. It hits letters, it doesn’t return o full size.

It won’t work on every small version. You have to have the blank space at the top of the mini keyboard to have it recognize the two fingers. When the blank space isn’t part of the mini board, you’re stuck.
